Take then off,
Positives:
1. Saves about 100 lbs when off
2. If someone bumps them in a parking lot, the leverage they have can rip out the corner of the camper. When I had my Hawk installed, I was advised to leave them in the place where I would store the camper as it usually exceeds $2000 to repair a mangled corner.
3. Provides attachment points for attaching a telescoping antenna mast
4. Provides attachment points front and back to hang an ABS plastic tube with fishing rods, poles for erecting tarps, antennas, and other lengthy objects I may want.
5. Makes it even harder for someone to transfer the camper to their truck. (Unlikely,, but I wanted 5 reasons.
Negatives:
1. Makes it impossible to remove camper from truck and leave it in campground to hold my spot while I explore. ??
2. Less likely to confuse camper with the Tardis or the Lunar Lander.
